Hassawi rice is a highly nutritional brown rice landrace native to the Eastern region of Saudi Arabia that has been cultivated for hundreds of years. The stem borer resistance was correlated with panicle weight and grain weight, which also showed a significant correlation with grain yield/plant. These traits can be effectively employed in a breeding program to confer resistance against stem borer infestation in rice. The results revealed that the non-additive dominance genetic variance was higher than the additive variance for all evaluated traits, indicating that non-additive genetic variances have a role in their inheritance. The broad-sense heritability estimates were high for all the studied traits. This work will contribute to achieving future rice breeding objectives by providing a rich background selection of potential parental materials. It will also provide important information for evaluation of genetic diversity in the local rice germplasm and its utilization in future rice genetic improvement programs.
